SHEARS.

Application led November 25, 1921. Serial No. 517,743.

To all ctv/tom 'it' may concern:

Be it known that l, ,CHARLES V. Jiissnr, a citizen ot the nited States. residing at Ivan, in the county oi Stejhens and State of Texas, have invented certain new and useful improvements in Shears, ot" which the following is a speciiication.

This invention relates to shears and has for an object to provide a new and improved bearing for shears of various types and sizes and for various purposes.

A further object ol the invention is to provide a roller bearing for shears with improved means for maintaining the bearing in organized condition.

llVith these and other objects in view, the invention comprises certain novel units, parts, elements, combinations, arrangements, functions and mechanical movements as disclosed Vinthe drawing, together with equivalents thereof, as will be hereinafter more fully described and claimed.

ln the drawings:

Fig. 1 is a View in side elevation-ot a pair of conventional domestic scissors.

Fig. 2 is a view oit said scissors in edge elevation.

Fig. 8 is a fragmentary view oi one of the blades showing the roller bearing in end elevation.

Fig. t is a transverse section taken through the pivoted connection between the blades. i

Fig, 5 is a further detailed sectional view showing more fully the roller bearings.

Like characters of reference indicate corresponding parts throughout the several views.

The improved bearing, which forms the subject matter of this application, is adapt ed to be associated with shears of various types and sizes and orvarious purposes. As shown in the drawing, a pair of domestic scissors is disclosed comprising the usual and ordinary blades A and B and pintle pin C of substantially the usual and ordinary type with their ordinary and accustomed handle features.. It is to be understood that the invention is in no way limited to the specific type of shears shown, such type being shown wholly and purely by way of illustration.

The blades A and B are each provided with an opening 10 concentric with, and larger than the pintle C and a plurality' of rollers 11 is introduced into the resultant annular space between the margins of suoli perforation and such pintle, as shown more particularly at Fig. 3. i

The length of these rollers 11 correspond to the thickness orn the blades, as shown more particularly atF ig. 2, and a ring or race 12 is interposed between theproXimate ends of the rollers. The rollers are further held in position against displacement by external covering members, here shown as plates 13 and 14, which are engaged respectively under the nut 15 and the head 16 of the pintle. These keepers 13 and 14 may be in the form of rings or races large enough to cover the perforation 10 of the blades, but preferably are made as elongated strips, as shown at Figs. 1 and 2, and rigidly secured to the handle parts of the blades preferably, though not necessarily, by welding, so that between the blade B and its keeper 13, space is provided for the reception of the blade A, while between the blade A and its keeper 14, space is provided for the reception of the blade B. By this means the keeper 13 of the blade B operates in unison with the blade AY and the keeper 14 of the blade A operates in unison with the blade B, and maintain the rollers against longitudinal displacement outwardly, their inne-r ends being engaged, as stated, by the washer 12.

ln assembling it is obvious that the rollers will be placed in position within the pertorations of the blades and the blades then crossed in operative position. and the pintle inserted, the nut 15 being screwed down to secure the necessary or desired cuti ting tension.

l claim: f

1. Shears of the type described, compris ing crossed blades, a pintle, a circular arrangement oi" rollers, said blades having enlarged perforations receiving said pintle and also adapted to receive the circular arrangement Vof rollers, said rollers encompassing said pintle, keepers iiXed to the blades, the free or remote ends of said keepers adapted to form closures for theterminals of said pintle receiving perforation, anda washer arranged between said blades and upon said pintle intermediate the adjacent ends of the rollers and engaged by the rollers.

2. A shear comprising crossed blades and a pintle, said blades being provided with perforations larger than and surrounding the pintle7 a Washe ntefposed be'weeii the blade and Coopeaing with the Washei te blades and positioned upon the pinle5 igoll- :event displacement ef the rollers from ers inserted m lie annular Spaces about the pefoiations. 10 the plntle Witlun the perfefaious of Jthe 1,11 tesimeny whereof l a; my signa- 5 blades and engaging the Washer and a keeper ture.
